Wait, you say the fecal came back clean but the vet still wants to give her something for that ? That''s a big NO ! You are the owner, tell them forget about it. Those meds. will make your dragon MORE dehydrated. No one takes meds. they don't need " just in case.", that's nonsense.
And another reason for your dragon acting strange that you just mentioned is that she sees the other dragon. When they see each other it can cause extreme anxiety and then they might display the symptoms you see, the don't eat or they hide. Please keep them completely out of each other's view.
I would be very leery of this vet, it seems likely that your dragon might be going in to a seasonal slow down and also is somewhat agitated because of seeing the other dragon.
